The naysayers, they don't mean a thing.

Everything is tennis for me, it's my career and it's entertainment, but it's also a business.

I don't want to give anyone an edge in my mind. Every time I walk out on the court, I have to feel I'm the best so I can compete well. A lot of times, my chief rival is just me.

I contribute my best in my sport and I also have a ton of respect for myself and my family.

I'm always on the court with my dad.

I remember watching the Olympics at home as a kid. It was one my Dad's dreams to win an Olympic medal.

I've learned about employee relations; I've learned about following your instinct. One of the biggest mistakes you can follow is not following your instincts, you know? A lot of times your instincts will tell you what to do if you have a good one. Now, if your instincts are terrible, then you ask for advice. But if you have good instincts, you definitely have to follow them, or else you regret them.
